Setting Up Your Aquarium
When it comes to setting up an aquarium for neon tetras, there are a few key factors to consider. Here are some tips to help you get started:
Aquarium Size
The size of your aquarium will depend on how many neon tetras you plan to keep. As a general rule of thumb, you should have at least 1 gallon of water per inch of fish.
For a small school of neon tetras, a 10-gallon aquarium should suffice. However, if you plan to keep a larger group of fish, you may need a larger aquarium.
Lighting
Neon tetras do not require intense lighting, but they do need a consistent light cycle. A basic aquarium light will suffice, and you should aim for 8-12 hours of light per day.
Filtration System
A good filtration system is essential for maintaining a healthy aquarium.
Look for a filter that is appropriate for the size of your aquarium and can handle the bioload of your fish. A hang-on-back filter or canister filter are both good options.
Aeration
Aeration helps to oxygenate the water in your aquarium, which is important for the health of your fish. You can use an air stone or a sponge filter to provide aeration.
Heater
Neon tetras are tropical fish and require a consistent water temperature of around 76-80°F.
A heater will help to maintain this temperature, and you should aim for a wattage that is appropriate for the size of your aquarium.
Aquarium Decor
Neon tetras prefer a heavily planted aquarium with plenty of hiding places. You can use live or artificial plants, as well as rocks, driftwood, and other decorations to create a natural-looking environment.
Substrate
A substrate is the material that lines the bottom of your aquarium. Neon tetras prefer a fine-grained substrate that is gentle on their delicate fins.

I remember spending hours carefully arranging plants and decorations in my first neon tetra tank, and it was well worth the effort. By following these tips, you can create a healthy and beautiful home for your fish.
Water Quality
As a neon tetra owner, it is important to maintain proper water quality to ensure the health and happiness of your fish.
Water quality can be affected by a variety of factors, including temperature, pH, and hardness. In this section, we will discuss each of these factors in detail.
Water Temperature
Neon tetras are native to warm, tropical waters, so it is important to maintain a consistent water temperature in your aquarium.
I personally keep my neon tetras at a temperature of 78°F, which seems to be the sweet spot for them. However, they can tolerate temperatures ranging from 72°F to 82°F.
Water pH
Neon tetras prefer slightly acidic water with a pH between 6.0 and 7.0. It is important to monitor the pH of your aquarium regularly, as fluctuations can cause stress and illness in your fish.
If you find that the pH of your water is too high or too low, you can adjust it using pH adjusters that are available at your local pet store.
Water Hardness
Water hardness refers to the amount of dissolved minerals in your aquarium water. Neon tetras prefer soft to moderately hard water, with a hardness level between 1 and 8 dGH.
If your water is too hard, you can use a water softener to bring the hardness level down.
Overall, maintaining proper water quality is crucial for the health and well-being of your neon tetras.
By keeping a consistent temperature, monitoring the pH, and adjusting the hardness level, you can create a comfortable and healthy environment for your fish.
How Often Should I Do Water Changes in Neon Tetra Tanks?
As an aquarium owner, one of the most important things you can do to keep your neon tetras healthy is to maintain clean water. Water changes are an essential part of this process, but how often should you do them?
As a general rule, it’s recommended that you change 10-20% of the water in your neon tetra tank every week. This helps to remove any built-up toxins and waste that can harm your fish.
However, the frequency of water changes can vary depending on a few different factors.
For example, if you have a heavily stocked tank with lots of fish, you may need to do more frequent water changes to keep up with the waste production.
Similarly, if you have a smaller tank, you may need to do more frequent water changes to maintain water quality.
Another factor to consider is the type of filter you have in your tank. If you have a high-quality filter that is properly sized for your tank, you may be able to get away with doing water changes less frequently.
However, if you have a smaller or less efficient filter, you may need to do more frequent water changes to compensate.
Personally, I have found that doing a weekly water change of around 20% works well for my neon tetra tank.
I also like to test my water regularly to make sure that the levels of ammonia, nitrite, and nitrate are within safe ranges. If I notice any spikes in these levels, I will do an additional water change to bring them back down.
In summary, maintaining clean water is crucial for the health of your neon tetras.
While a weekly water change of 10-20% is a good starting point, the frequency of water changes may need to be adjusted based on the size of your tank, the number of fish you have, and the quality of your filter.
Regular water testing can also help you determine when additional water changes are necessary.
Neon Tetra Tank Mates
When it comes to selecting tank mates for your neon tetras, it’s important to consider their peaceful nature and small size. Here are a few compatible species:
- Otocinclus Catfish: These small catfish are peaceful and can help keep your tank clean by eating algae.
- Cherry Shrimp: These colorful shrimp are small and peaceful, making them great tank mates for neon tetras.
- Corydoras Catfish: These catfish are also peaceful and come in a variety of colors and patterns.
- Ember Tetras: These small, colorful fish are similar in size and temperament to neon tetras, making them great companions.
It’s important to avoid aggressive or larger fish that may harm or intimidate your neon tetras. Avoid species such as cichlids, bettas, and larger tetra species.
Personally, I’ve had success keeping neon tetras with cherry shrimp and otocinclus catfish in my own aquarium.
It’s always a joy to watch these peaceful species interact and thrive together in a well-maintained tank.
How Many Neon Tetras Should be Kept Together?
When it comes to neon tetras, it is important to keep them in groups. These fish are social creatures and thrive in a community setting. But how many should you keep together?
As a general rule, it is recommended to keep at least six neon tetras together. This allows them to establish a hierarchy and reduces stress levels.
However, you can keep up to 10-12 neon tetras in a single tank, as long as the tank is large enough to accommodate them.
When choosing the number of neon tetras to keep together, it is important to consider the size of your tank.
Neon tetras are small fish, but they still need plenty of swimming space. A good rule of thumb is to provide at least 1 gallon of water per neon tetra.
It is also important to note that neon tetras are not aggressive fish. They are peaceful and do well with other non-aggressive species.
However, it is best to avoid keeping them with larger, more aggressive fish that may view them as prey.
Personally, I have a 20-gallon tank with 10 neon tetras, and they seem to be thriving.
They are constantly swimming around and interacting with each other, and their vibrant colors add a beautiful touch to my aquarium.
I highly recommend keeping neon tetras in a group, as it not only benefits their physical health but also their mental well-being.
Neon Tetra Diet
Feeding your neon tetras a balanced diet is essential for their health and longevity. In this section, we’ll cover the types of food that are best for neon tetras and the recommended feeding schedule.
Types of Food
Neon tetras are omnivores, meaning they eat both plant and animal matter. A varied diet is important to provide them with the necessary nutrients. Here are some types of food that are suitable for neon tetras:
- Flake food: This is a staple food for neon tetras and should make up the majority of their diet. Look for high-quality flake food that contains a variety of ingredients, including spirulina and other plant matter.
- Frozen or live food: Neon tetras enjoy eating brine shrimp, bloodworms, and other small aquatic invertebrates. These can be offered as a supplement to their flake food diet.
- Veggie matter: Neon tetras also benefit from eating vegetable matter, such as blanched spinach, zucchini, or peas. These can be given as a treat once or twice a week.
Feeding Schedule
It’s important to feed your neon tetras small meals several times a day rather than one large meal. This will help prevent overfeeding and keep their digestive system healthy. Here’s a recommended feeding schedule:
| Time of Day | Food |
|---|---|
| Morning | A small pinch of flake food |
| Afternoon | A few brine shrimp or bloodworms |
| Evening | Another small pinch of flake food |
Remember to only feed your neon tetras what they can consume in a few minutes. Overfeeding can lead to health problems and poor water quality in your aquarium.
Personally, I have found that my neon tetras love eating live brine shrimp. Whenever I offer it to them, they become very active and excited.
However, I make sure to only give it to them as a treat once or twice a week, as it can be expensive and time-consuming to maintain a constant supply of live food.

Breeding Neon Tetras
Breeding neon tetras is an exciting and rewarding experience for any fish enthusiast. Here are the steps you need to follow to successfully breed neon tetras.
Breeding Setup
To breed neon tetras, you will need a separate breeding tank. The tank should be at least 10 gallons and should be equipped with a sponge filter.
You will also need a heater to keep the water temperature between 75-80°F. Place some live plants in the tank, like java moss, to provide hiding places for the fry.
Breeding Process
To start the breeding process, you will need a male and female neon tetra. You can tell the difference between the two by looking at their bellies.
The female’s belly will be rounder and larger than the male’s. Once you have a male and female, condition them with a high-protein diet for a week.
After that, place them in the breeding tank and wait for them to spawn. The female will lay her eggs on the plants, and the male will fertilize them.
After spawning, remove the adult tetras from the breeding tank to prevent them from eating the eggs. The eggs will hatch in 24-36 hours, and the fry will start swimming after another 3-4 days.
Caring for Fry
Once the fry start swimming, you will need to feed them small amounts of infusoria or liquid fry food several times a day.
As they grow, you can start feeding them baby brine shrimp or crushed flakes. It’s important to keep the water in the breeding tank clean and well-oxygenated.
Perform daily water changes of 10-20% to keep the water quality high. I remember the first time I successfully bred neon tetras.
It was such an amazing feeling to see the tiny fry swimming around in the tank. Breeding neon tetras requires patience and dedication, but the end result is definitely worth it.
